    摘要: An in-line filter includes a hollow base having first and second wall portions formed between its ends and a filter element mounted on the base. During use, the base of the filter is disposed inside a standard tubing connector, and the wall portions are resiliently deformed by the tubing connector such that the surfaces of the wall portions are pressed into sealing contact with internal surfaces of the tubing connector. The filter element connected to the base is disposed inside the tubing connector and/or tubing to which the tubing connector is attached. According to another form of the invention, a filter element includes a hollow base having a radially outwardly extending flange. An annular sealing member is mounted on the flange, and a filter element is mounted on the base. During use, the base of the filter is disposed inside a standard tubing connector, and the sealing member is pressed into sealing contact with internal surfaces of the tubing connector and with the flange.

    摘要: A filter for subterranean use includes a filter body containing a filter medium, and a restraining member disposed around the filter body. The inner periphery of the restraining member is sufficiently close to the outer periphery of the filter body to prevent the filter body from being damaged by radially outward forces encountered during operation of the filter within a well.

    摘要: A filter for subterranean environments includes an inner support member, a filter body containing a filter medium disposed around the inner support member, and at least one end connector connected to a lengthwise end of the filter body and sealed against the inner support member without being welded to the inner support member. The end connector may be restrained from movement relative to the inner support member in a lengthwise direction of the inner support member, without being welded to the inner support member, to resist axial forces acting on the filter during installation or operation in a well. Alternatively, the end connector may be capable of movement with respect to the inner support member in a lengthwise direction of the inner support member to enable the filter to undergo thermal expansion without damage to the filter body or other portions of the filter.
